With the exception ofendless chains, thetransmission power tablesin this catalog are basedon use with connectingparts (connecting links oroffset links).See page 12 for details on
connecting parts.
This drive chain catalog explains how to select, install and maintain all listed Tsubaki Roller
Chains. Numerical figures are indicated in both SI and gravimetric units.
Read through this catalog before use to ensure proper selection and usage. Also, carefully
inform persons involved in installation and maintenance of all pertinent matters.
NOTE
NOTE
Ordinary Transmission
Shuttle Traction
When using a roller chain in lifting applications, keep clear from underneath the load.
If there is the possibility of serious accident or death in the event of roller chain
breakage during lifting or other applications, install reliable safety devices to prevent
accidents.
Inspect and replace worn roller chain periodically.Roller chains can break and climb up on the sprocket from wear elongation.
(Lubrication can extend service life against wear elongation. Tsubaki also offers
lube-free drive chains that deliver long-lasting service without lubrication.)
Overload may cause roller chain to break. (Avoid breakage by properly selecting
products with consideration of inertia, etc. Tsubaki offers heavy-duty drive chains in
identical sizes that deliver the high strength of larger chains.)
Roller chains can break due to corrosion and other environmental conditions. (Avoid
breakage by preventing exposure to corrosive liquids, atmospheres, etc. Tsubaki
offers excellent corrosion-resistant drive chains.)
Correctly install roller chain to avoid misalignment or uneven wear and possible breakage.

http://slidepdf.com/reader/full/tsubaki-drive-chain-sprockets 9/210
Accommodate large speed reductions/increases (usually up to 1:7).
Chains can accommodate long shaft center distances (normally less than 4 m), and are more versatile.
It is possible to use chain with multiple shafts or drives with both sides of the chain.
Easy installation and replacement (easy to cut and connect chains).
Drive use is possible even when shafts are vertical, as long as the chain receives support in short
distances between the shafts.
Standardization of chains under the American National Standards Institute (ANSI), the International
Standardization Organization (ISO), and the Japanese Industrial Standards (JIS) allow ease of
selection.
The sprocket diameter for a chain system may be smaller than a belt pulley while transmitting the
same torque.
Sprockets are subject to less wear than gears because sprockets distribute the load over their many
teeth.
High shock absorbency compared to gears.
Chains have speed variation, called chordal action, which is caused by the polygonal effect of the
sprockets.(Shock can be reduced under the same speed ratio by either reducing the chain pitch or
increasing the number of sprocket teeth.)
During transmission, a method of lubrication suitable to the chain's speed is necessary.
Chains wear and elongate. Measures for adjusting chain slack need to be considered.
Chains are weak when subjected to loads from the side. They need proper alignment.

The following table compares roller chains to other power transmission mechanisms such as
toothed belts, V-belts and gears. Generally speaking, roller chains are often used as
economical power transmission suited to low speed and high loads. However, it is also
possible to use chain in high-speed applications such as camshaft drives for automobiles.

This is the minimum tensile strength determined by ANSI Standard. If a roller chain breaks
from a tensile load below this value, then it is non-compliant. With multi-strand roller chain, the
single strand value is multiplied by the number of strands. (ANSI B 29.100)
This is a fracture load reading obtained after a long period of actual tensile strength testing of
a large number of chain strands. Naturally, a roller chain may actually break at a higher or
lower value than this, so it does not represent a guaranteed value. This value varies
depending on the manufacturer.
As shown in Fig. 2, a roller chain with over five links is fixed at both ends by clevises and is
stretched until breakage occurs (JIS B 1801-2009). The type of fracture is indicated by
breakage of the roller chain or failure of its parts (Fig. 3.)
This is a minimum value determined by
statistical processing at Tsubaki. If any
roller chain fractures by a tensile load
below this value, then it is
non-compliant. This value variesdepending on the manufacturer.
Note that strength of offset links may be
lower than the chain itself.
(Refer to each product page for details.)
The maximum allowable load of roller chain (excluding Stainless Steel Chain and Engineering
Plastic Chain*) is the value derived from the lowest fatigue limit. When a load lower than this
value is repetitively applied to the roller chain, fatigue failure will never occur.
Tsubaki standards and catalog values are for 107 repetitions, or 2Pa. In other words, if
Tsubaki's maximum allowable load is indicated as maximum load (Pmax), then values in this
catalog would increase 10%.
According to the former JIS B 1801-1997, the maximum allowable load indicates abreakage load of Pmax = (Pm + Pa) = 2.2Pa at a frequency of 5 106, when a new
roller chain with over five links receives a repetitive load in linear operation. (Fig. 4)

RS Roller Chain, SUPER Roller Chain, Heavy Duty Chain, and Low Noise Drive Chain
kilowatt ratings tables show kW values for 15,000 hours of operation using a two-shaft drive
and 100 pitches of roller chain under conditions 1 - 5 below.
The kW ratings table of Lambda Chain is based on conditions 1 - 4 and shows kW rating
values when Lambda Chain is used with two shafts. Lambda Chain has more than seven
times the wear elongation of Standard RS Roller Chain operated without lubrication (#120 and
#140 are over 2.5 times). X-LAMBDA has more than five times the wear elongation life of
Lambda Roller Chain.

The chains are operated under ordinary conditions where the ambient temperature is -10 - +60
(+14F to +140F) and there is no abrasive dust.
There are no negative effects from corrosive gasses or high humidity.
The two shafts are level and the chains are properly installed. (See item 4 on pg. 194.)
There is minimal fluctuation in load during transmission.
The recommended lubrication system and lubricant shown in the kW ratings tables is used for RS Roller
Chain and Super Roller Chain. (See pgs. 192 - 193.)
6. Moment of Inertia (I / J / GD2)
7. Total Length Tolerance of Roller Chain
8. Elastic Elongation of Chain under Load
Length test method and length tolerance are specified in JIS B 1801-2009. The length
tolerance of any individual size when subjected to a measured load (e.g. 500 N [50.99 kgf] for
RS 80) specified in JIS is 0 to +0.15% of the reference length. The reference length is
calculated by multiplying the reference pitch (P) by the number of links. (Applicable to
products bearing a JIS identification number.)
An elastic elongation curve of a chain under load looks as shown below. Values shown here
are the standard references for single-strand RS Roller Chains. Actual values may slightly
differ. Do not apply loads greater than the maximum allowable load to roller chains.

5. Kilowatt Ratings Table
Moment of inertia is used to show the degree of inertia in rotational movement; in other words,
"rotation difficulty", or "rotation ease." This is equivalent to the mass (weight) of the object
being used for straight-line transmission.
Moment of inertia is shown in the SI units table as:
I = mk2 (kgm2 m: mass of rotating body k: turning radius)
It is shown in the Gravimetric units table as:
J = (kgfms2 G: mass of rotating body G: gravitational acceleration).
Although, GD2 = 4GJ (D: diameter of rotating body) is generally being used now in place of
moment of inertia.

Roller Chain Construction
1. Basic Structure (Photo: RS Roller Chain)
The plate bears the tension placed on the chain. Usually this is a repetitive load, butsometimes it is accompanied by shock. Therefore, the plate must have not only great static
tensile strength, but also must hold up to the dynamic forces of load and shock.
The pitch, roller diameter, andinner width of the inner linkare considered the basic threedimensions of a roller chain.When these dimensions areidentical, a roller chain andsprocket are dimensionallycompatible.
Basic Three Dimensions
When the shafts and holes arefitted together, there is acontinuous loose fit. This is afit where the range of tolerancefor the hole is larger than therange of tolerance for the shaft(pin or bush).
*1Slip Fit
When the shafts and holes are
fitted together, there is a
continuous interferential fit. Thisis a fit where the range of
tolerance for the hole is smallerthan the range of tolerance for
the shaft (pin or bush).
*2Press Fit
Spring clips, cotter pins andspring pins are essential partsthat prevent connecting platesfrom falling off, maintaining
the strength of the chain itself.Always install these parts.
The pin is subject to shearing and bending forces transmitted by the plate. At the same time, it
forms a load-bearing part, together with the bush, when the chain flexes during sprocket
engagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,
and sufficient endurance against shock and wear.
The bush is subject to complex forces from all parts, especially from the repetition of shock
loads when the chain engages the sprocket. Therefore, the bush needs extremely high shock
resistance. In addition, the bush forms a load-bearing part together with the pin, and as such
requires great wear resistance.
The roller is subject to impact load as it strikes the sprocket teeth during chain engagement
with the sprocket. After engagement, the roller changes its point of contact and balance. It is
held between the sprocket teeth and bush, and moves on the tooth face while receiving a
compression load. Therefore, it must be resistant to wear and still have strength against
shock, fatigue and compression. RS11 / 15 / 25 / 35 do not have rollers.
Two bushes are press fit into two inner plates, and rollers are inserted to allow rotation around
the outside of the bush. This is the same for single-strand and multi-strand chain.
The pin link consists of two pins that have been press fit into two outer plates. With
multi-strand roller chain, a middle plate is added to the pin link. The middle plate is slip fit for
standard RS Roller Chain and press fit for Super Roller Chain.

2.1 Connecting Links
12
Roller Chains are usually made up of a number of connected links in an endless formation, or used by fixing the chain ends, but
the need for connecting links will eventually arise. Although offset links can be used when there are an odd number of links in
the roller chain, please use a design that requires an even number of links as much as possible. Please note that connecting
links and offset links are normally coated with an anti-rust agent only. Always thoroughly lubricate pin and bush when
assembling.

*1: The operating temperature range of pre-lubricated chains (those coated with oil when delivered) is -10 to +60 (-40 to +60
for KT specification).Chain kW ratings do not decrease until 150
. To use in +60 to 150
environments, apply a high temperature lubrication. For details and precautions inusage, see "Temperature Selection Method" (page 188) and "Roller Chain Lubrication" (page 192).
*2. Lambda Chain KF Series gives better lubrication performance in high temperature ranges (from ambient temperatures to ~230
. When using in the 150
- 230
range, refer to pg. 188 for temperature selection methods.*3. RS11-SS-1 comes lubricated.*4. Operating temperature range when using stainless steel rollers. Operating temperature range for plastic rollers is -20
to 80

3. Matched and Tagged ChainDeviations in chain length exist due to the manufacturing
tolerances of the parts. When chains are to be used in parallel
and minimizing the relative difference in the lengths is necessary,
request a "matched and tagged" chain.
Note: A separate charge is required for a length matching.
Chains whose total length exceeds one unit (3048mm) are called
long length formations. Chains that exceed the lengths below are
super long length formations and are delivered connected in
special boxes. Additional fees apply.

RS ® Sprocket Guide and Ordering Example
RS Sprockets are for RS Roller Chain (JIS/ISO standards).
With the Pilot Bore Series, the shaft hole is the pilot bore, and so will require processing before use.
(RS25 sprockets have an H8 pilot bore and are tapped. Other sizes have an H10 pilot bore.)

Tsubaki also offers single dual (SD) type sprockets, which accommodate two
strands of chain. Sprockets with small numbers of teeth have hardened teeth,
while those with large numbers of teeth are not heat treated.
Features hardened teeth for sprock-
ets with a large number of teeth.
Strong Series sprockets are high
quality sprockets with teeth hardened
to the appropriate quality standards.
*The classification of small or large numbersof teeth varies with sprocket size.See each sprocket’s dimensional chartfor details.

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key
bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. Sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 16 for
9T, 22 for 10T, 24 for 12T and 28 for 13T.4. Sprockets with 42 or more teeth do not have hardened teeth, but the Strong Series of
sprocket with hardened teeth can be made-to-order.

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. The outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. 1B-type sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 21 for 9T, 25 for 10T, 30 for 11T and 32 for 12T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.
6. Welded specification: machine-structural carbon steel (teeth) and structural rolled steel (hub)

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. The outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. 1B-type sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 27 for 9T, 37 for 11T, 42 for 12T and 4 7 for 13T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.6. Welded specifications, machine-structural carbon steel (teeth) and structural rolled steel (hub).

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. Outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. 1B-type sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 32 for 9T, 37 for 10T and 45 for 11T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.
6. Models with approximate masses in bold have one hanging hole processed. See the diagram on the right for information.

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. Outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. 1B-type sprockets marked with an * have an outer groove around the hub. Groove outer diameter is 44 for 9T.5. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.
6. Models with approximate masses in bold have one hanging hole processed. See the diagram on the right for information.7. Welded specifications, structural rolled steel (teeth and hub).

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. Outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. For single-strand sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.5. Models with approximate masses in bold have one hanging hole processed.
See the diagram on the right for information.

Note: 1. Maximum bore diameter is the typical range. Determine bore diameter and key bearing pressure based on general mechanical design.2. Models in shaded areas have hardened teeth.3. Outer diameters above are given for the 1B type. Diameters vary slightly for all other types.4. For sprockets without hardened teeth, the Strong Series of sprocket with hardened teeth can be made-to-order.
5. Models with approximate masses in bold have one hanging hole processed.
See the diagram on the right for information.

*The operating tempera-ture range for Lambda and X-Lambda Chain is 150.
*Data in the 230 rangeprovided for referenceonly. Do not use Lambda Chain at 230.
*Kilowatt ratings will drop to3/4 of the listed catalogvalues when using in the150 - 200 range. Selecta chain to match your operating temperature.
*Kilowatt ratings will drop to1/2 of the listed catalogvalues when using in the200 - 230 range. Selecta chain to match your operating temperature.
A roller chain’s wear life varies depending on the chain speed and load acting on it, the number of teethon the sprocket, operating conditions and temperature, and so on.The graph below provides a rough guide to roller chain wear life.*Wear life for Lambda Chain is +0.5% elongation.

Precautions for UseDust in the bush accelerates wear. Wet environments can cause the oil in the oil-impregnated bush to leak. Bushes are also coated with lessrust-preventing oil, causing early rusting.Bush oil can leak in a vacuum, decreasing wear resistance. Do not use in a vacuum.The life of the chain will decrease dramatically if oil in the oil-impregnated bush is depleted. (See "(9) Lambda Chain Life" on pg. 150.)KW ratings for double strand Lambda Chain (Double strand coefficient)The coefficient of a double strand chain with the same part dimensions of a single strand chain is 1.4. To achieve the same coefficient of 1.7of a multi-strand RS Roller Chain, use a Heavy Duty Lambda Chain with thicker outer and middle plates. In any event, sprockets must becustomized. Double strand RS-type sprockets cannot be used.Double-strand Lambda Chain pin lengthBecause the inner plate is thicker than that of an RS Roller Chain, the pin is longer by an equal amount (L1 and L"). Check for machineinterference.

Nickel-plated seriesDo not use nickel-plated chain if the chain will come in direct contact with food or where coating flakes or wear dust can contaminate food.
Also, in non-food applications, appropriately cover the chains or contact Tsubaki about chain selection if using in environments where
coating flakes and wear dust present problems. Though nickel is not subject to the Food Sanitation Law or the Industrial Safety and Health
Law, plating on sliding parts can peel.

ConnectingUse a connecting link (with felt seal) to connect X-Lambda Chains. Set the felt seals on the inside of boththe outer plate and connecting plate (Fig.1). (For chainconnecting instructions, see pg. 140.)
Precautions for useBecause of its felt seals and inner plates that are thicker than RS Roller Chain’s inner plates, the pins are longer (L1 and L2). Check forequipment interference.Offset links are not available for X-Lambda Chains. Chains should be designed with an even number of links.Due to oil in the felt seal, more oil adheres to the surface of X-Lambda Chains than regular Lambda Chains.

2. Uses
Tsubaki’s Heavy Duty Roller Chains come in a wide array of products. Their high maximumallowable load make them commonly used in compact transmission systems.
Use Tsubaki Heavy Duty Roller Chains when capacity exceeds that of RS Roller Chains, such as in:1. Harsh environments where the chain will be subjected to heavy impact.2. Compact drives for equipment or machines that must work in tight spaces.3. When higher transmission power, allowable load or tensile strength is required.4. When a lower rate of elastic elongation is required.
1. Extensive line-up with outstanding reliability

Product Line-up
Super Chain
RS-HT Chain
Super-H Chain
Ultra Super Chain
Super Chain has the same three basic dimensions of RS
Roller Chain, but it has a thicker waist that provides a 30%increase in maximum allowable load over RS Roller Chain.
Suitable for situations where RS Roller Chain would suffer
fatigue breakage, and allows users to go one size down.
The outer and inner plates are one size thicker than on RS
Roller Chains.
RS-HT Chain has 20% greater tensile strength than RS Roller
Chain, and so is ideal for applications requiring high tensile
strength and low elastic elongation.
Features inner and outer link plates shaped the same way as
Super Chain that are one size thicker than RS Roller Chain.
This gives Super-H Chains a higher allowable load and fatigue
strength for applications requiring shock absorption.
Inner and outer link plates are oval and one size thicker than RS
Roller Chains. Ultra Super Chains have the highest allowable
load, tensile strength, and shock absorption of any Tsubaki drive
chain, and are suitable for drives requiring a compact design.

Uses a connecting link that is easy to attach and remove,yet still has the same strength as the rest of the chainthanks to Tsubaki’s ring coining process.
Super Chain can even be used with an odd number links tocreate the perfect length for your needs. (4POL max.allowable load and kW ratings are 90% of the base chain.Only available for single strand chain.)

Pins are treated with a non-strength degrading surface treatment to protect against pitting corrosionthat leads to fatigue breakage, making it highly effective in environments that readily promotecorrosion, such as outdoor or coastal applications.
APP Series
Safety precautions when using Surface Treated Drive ChainsDo not use NP / NEP Series Surface Treated Drive Chains if the chains will come in direct contact with food or where coating flakes
or wear dust can contaminate food. The specific gravity of flaked NEP film is lighter than water and will float.
Also, in non-food applications, either appropriately cover the chains or contact Tsubaki about chain selection if usage is planned in
environments where coating flakes and wear dust present problems. Though nickel is not subject to the Food Sanitation Law or the
Industrial Safety and Health Law, plating on sliding parts can flake.
These roller chains are made of 304 stainless steel (301 stainless steel clips). They offer greatercorrosion resistance than RS Roller Chains and RS Surface Treated Roller Chains, and can be used
in water and in corrosive atmospheres that are acidic or alkaline, as well as in low or hightemperatures (-20 to 400˚C). 304 stainless steel is only marginally magnetic. Some magnetismexists only due to the cold-forging process.
SS Series
Corrosion Resistant Roller Chains

Stainless Steel Roller Chains
Surface Treated Roller Chains
These are surface-treated RS Roller Chains.
These roller chains are made of stainless steel. (See pg. 189 regarding the corrosion resistance of stainless steel drive chains.)
Basic stainless steel chain using SUS304 equivalent.
For protection against pitting corrosion fracture.
−20400
These roller chains are made of 316 stainless steel (301 stainless steel clips on RS25NS, and 304stainless steel cotter pins on RS80NS). They are suited for applications that require higher corrosionresistance than SS chains. Except for the clips, they are non-magnetic.
NS Series Highly corrosion resistant stainless steel chain using SUS316.
−20400
AS Series
LSC Series
The pins and rollers of these roller chains are made of precipitation-hardened, tempered stainlesssteel, while the plates and bushes are 18-8SUS (304 stainless steel clips are 17-7SUS (301stainless steel)). They have a maximum allowable load that is 1.5 times that of SS chains. Corrosionresistance is slightly less than that of SS chains. AS chains are suited for applications that requirecorrosion resistance, heat resistance, and smaller sizes / higher kilowatt ratings than SS chains.Because of its precipitation-hardened stainless steel, the chains are magnetic.
Stainless steel chain with 1.5 times the allowable load of SS Series.
−20400
Lube-free, long life stainless steel chain.
−20100**Operating temperature range with stainless steel rollers.Engineering plastic rollers: -20 to 80
NP SeriesThese chains are RS Roller Chains with nickel plating. The nickel plating not only improvesappearance, but also adds a small degree of corrosion resistance. Therefore, they can be used inapplications where there is exposure to water. Bear in mind when making your selection thatmaximum allowable load is approximately. 15% lower than with RS Roller Chains.
Nickel plating provides an attractive appearance.
−1060*Maximum 150 possible when used with a lubricant suited to the temperature range.
NEP SeriesNEP Chain is a Coating chain with a high corrosion resistance thanks to its zinc coating base andtwo different kinds of special surface coatings for rollers and other parts. The zinc coating andspecial surface coatings protect the chain body from corrosive environments, giving it superior rustprevention. NEP Chain has superior anti-rust capabilities over previous WP or DP chains, reducingits load on the environment.
Uses a special coating for outstanding corrosion resistance.
−1060*Maximum 150 possible when used with a lubricant suited to the temperature range.
RoHS compliant
This lube-free roller chain uses 18-8SUS (SUS304 equivalent) for the base chain and specialengineering plastic sleeves in the bush. Suitable for situations requiring greater wear resistance thanSS Series. Engineering plastic rollers also available.

Poly Steel Chain that conforms to BS standards.
BS-PC (BS Standard Series)
Pre-Delivery Lubrication
SS Series and NS Series Stainless Steel Roller Chains, Titanium Roller Chains, and Curved Stainless Steel Roller Chains are
not lubricated before delivery. Always lubricate your chain before use, except when chains are to be used submerged in or in
contact with water. If chains are not lubricated for use, then they may suffer articulation problems prematurely.
The maximum allowable load is calculated under lubricated conditions (including water lubricant).
*RS11-SS-1 chain is lubricated.
Poly Steel ® Chains
The pins and outer plates of these chains are made of titanium, while the inner plates are of aspecial engineered plastic (matte white); therefore they are suited for applications in which PCChains have insufficient corrosion resistance. They can be used in temperatures of –20 to 80˚C. Fordetails on corrosion resistance selection, see pg. 188. Bear in mind when making your selection thatmaximum allowable load is about 60% that of PC Chains.
PC-SY (Super Chemical Resistance Series)
The pins and outer plates of these chains are made of 304 stainless steel (301 stainless steel clips),while the inner plates are of engineered plastic (white). They are lube-free, low noise (5 dB less thanRS Roller Chains) and lightweight (50% of RS Roller Chains). They can be used in temperatures of–20 to 80˚C. For details on corrosion resistance selection, see pg. 188.
PC (Standard Series)
These chains emit 6 to 8 dB less noise than pre-lubed RS Roller Chains (in-house comparisontesting).
Low Noise Roller Chains
These roller chains have a wide sideflex due to its original pin / bush construction and the largeclearance between its plates. Curved transmission is easy using RS-type standard sprockets.
Curved Stainless Steel Roller Chains
Titanium chains are non-magnetic and offer high corrosion resistance. For details on corrosionresistance selection, see pg. 188.
Titanium Roller Chains
These chains can be used in lower temperatures than RS Roller Chains yet deliver the same allowableload (when using an F-type connecting link). Expect a 20% reduction in strength when using an M-typeconnecting link.

SS Series Stainless Steel Roller Chains are not lubricated before delivery. Always
lubricate your chain before use, except when chains are to be used submerged in or in
contact with water. If chains are not lubricated for use, then they may suffer articulation
problems prematurely.
The maximum allowable load is calculated under lubricated conditions (including water
lubricant).

Corrosion Resistant Roller Chains
LSC Series Stainless Steel Drive Chain
*Made-to-order product.
See pg. 122 for information on corrosion resistant sprockets.
Tsubaki’s LSC Series Stainless Steel Drive Chain provides long life not only in dry environments, but also incontact with water or even underwater. Stainless steel chains are an ideal choice in production lines with awashdown process; in the food industry, where water is often part of the production process; in sanitary andpharmaceutical packaging industries; and in a wide variety of other industries.
Uses a special plastic sleeve for the bearingFeatures black engineering plastic sleeves betweenSS Series stainless steel chain pins and bushes.Rollers can be either stainless steel or engineeringplastic (white).
Stainless steel rollers provide over fourtimes the wear life of SS Series StainlessSteel Chain. Engineering plastic rollersprovide over ten times the wear life.
When disassembling the chain, be careful that the engineering plastic sleeves(black pipe) between the pins and bushes do not fall out. Also, ensure that thesleeves are present between the pins and bushes when connecting.

Depending on the conditions of use, if steel roller chains are used with stainless steel sprockets, the roller may prematurely
wear due to galvanic corrosion. Please avoid this set up as much as possible.
Compared to single-strand chain, the inner link of multi-strand chain is slightly less corrosion resistant (based on in-house
testing).
Precautions in Usage
4. 2-pitch offset links are not available.5. Please contact a Tsubaki representative for information regarding RS180 and above chains.

Anti-Pitting Roller Chain
Outstanding performance in atmospheres conducive to pitting corrosion
Note: Pitting is a type of localized corrosion affecting metal surfaces. Pits form toward the interior, and if pitting occurs on pin surfaces, that pin can quickly leadto fatigue breakage and chain failure.
Pins are treated with a special surface treatment to
protect against pitting corrosion that leads to fatigue
breakage, thus preventing strength loss. This treatmentis highly effective in environments that readily promote
corrosion, such as outdoors or in coastal applications.
Features No strength loss! Eco-friendly chrome-free!Special surface treatment does not use hazardoushexavalent chromium.
Same as standard steel chain.
Example applications
Examples of fatigue breakage caused by pitting corrosion
Applicable models
Chain number
APP Chains are ideal for atmospheres that readily promote corrosion.
Outdoor uses Coastal or riverside uses When regular lubrication is difficult
Bucket elevators Transfer cranes and other port machinery
Because equipment is used outdoors,rain can infiltrate gaps in covers, creatingconditions that promote pitting corrosion.
Pitting readily occurs in equipmentexposed to salty air or saltwater spray.
Chain: RS240 Equipment: Port container carrier

Titanium Roller Chains are not lubricated before delivery. Always
lubricate your chain before use, except when chains are to be
used submerged in or in contact with water. If chains are not
lubricated for use, then they may suffer articulation problems

Less factory noise for a better work environment.A low noise function is added to machinery and equipment used for manufacturing, and contributes toupgrading and improving their overall image.Belts were considered as a countermeasure for noise; however, there are many limitations in terms ofapplication, strength and overall cost. Low Noise Chain is the perfect countermeasure.Recommended for applications where silence is a major concern, such as stage lifts used in theaters.
Dimensional specifications are the same as for RS Roller Chain.Note: There are limits on drive power; check kW ratings tables on pgs. 90–92.
Interchangeability
Use the General Selection Method (the kilowatt ratings tables on pgs. 90–92).See selection pages for more details.
Selection
–10°C to 60°C
Operating temperatures
200 m / min (max.)
Allowable chain speed
Can be used with standard RS sprockets.If the chain cannot be sufficiently lubricated, choose sprockets with hardered teeth specifications.
Sprocket
Tsubaki's uniquely structured spring rollers are used for the chain rollers. When Tsubaki's Low Noise Roller
Chain engages the sprocket, the spring roller deforms and absorbs the force of impact, reducing impact
noise between chain and sprocket for lower noise levels. Compared with Tsubaki's standard RS Roller Chain
(pre-lubricated), noise levels of Low Noise Roller Chain are 6 - 8 dB lower. (In-house comparison testing)

Curved Stainless Steel Roller Chains are not lubricated
before delivery. Always lubricate your chain before use,except when chains are to be used submerged in or in
contact with water. If chains are not lubricated for use,
then they may suffer articulation problems prematurely.

External plate dimensions and thickness are
the same as for the outer plates of RS Roller Chain with
the same pitch, while the pin diameter is almost the
same.
Middle plate
ConstructionLeaf chains are also commonly called balance chains. The mostbasic type of steel chain, they consist of just plates and pins.Conforming to JIS specifications and suitable for use in low-speedequipment, leaf chains are mainly used for lifting, counterweights,and motion drives.The plates are connected by pins and take the strain when load isapplied. Pins are press fitted to outer plates and riveted. However,a slip fit* is used with middle and inner plates and pins.The pins pass between the plates and have to withstand the bulk ofthe shear forces resulting when the chain is under tension andmove freely within the inner plate holes when the chain articulates.
* Slip fit
When a pin is fitted to a hole, some play is normally allowed. The tolerance
range of the hole diameter is larger than the tolerance range for the pin diameter.
* Press fit
When a pin is fitted to a hole, the pin is normally tight against the hole. Thetolerance range of the hole diameter is less than the tolerance range for the pin
diameter.

Types
End links
There are two types of leaf chain: AL for light loads and BL for heavy loads. The dimensions and plateconfiguration for each is different.
AL Type
Plate width is the same as for the inner
plates of RS Roller Chain of the same pitch. Plate
thickness is the same as for one pitch larger RS roller
chain, as is pin diameter.

Precautions for Use
Recommended lubrication: ISO VG 100 to 150 (SAE30 to SAE40)
Lubrication method:
Lubrication period:
Lubricate regularly to prevent pin rotation
and improve wear life.
Avoid use in corrosive environments.
Check for elongation.Replace chain when elongation reaches allowable
elongation limit (3%).
Guidelines for checking chain elongation
Note: Pitch elongation limit can be quickly checked with achain elongation scale. For details, see pg. 120.
In order to prevent chain backlash, measure with slight tension on the chain.
Use calipers to measure the distance between the outside L1 and inside L2 of the pins for
the portion of the chain articulating around the sheave as shown in the illustration to obtain
Obtain chain elongation percentage using the following formula.
- Standard lengthStandard length
Chain elongation = 100(%)
Standard length = Chain pitch x No. of links
Measure between 6 to 10 links
Ordering
Specify the chain number, number of links, chain endspecifications, and link pin requirements.
The following specifications exist for each end of the
chain. Specify your preference.
1. Connecting link
2. End link (Outer and inner end link hole
diameters are the same)
3. Outer link
4. Inner link
With orders for an odd number of links, each end will be given
an inner link. With orders for an even number of links, one end
will have an inner link and the other a connecting link.
If no chain end specification
With the chain loose, use a brush or oil stick to
sufficiently lubricate the outer chain, making sure
that oil also penetrates between plates.
Lubricate regularly so that sliding sections between
pins and inner plates do not dry out.
1.
2.
3.
Dimensions for L in the table above assume that only the rivet pin is
wound around the sheave. If a connecting pin is wound around the
sheave, use L 2 (L2) x 1.05. Design L with an appropriate width while
minding the installation precision of the sheave.
Use sheaves made of machine-structural carbon copper. (S45C, etc.)
Use heat-treated HRC (35 to 40) for high repetition applications.
Wipe immediately when there is contact with water and
lubricate well. When there is a possibility of corrosion,
apply a large amount of grease to the surface of the
chain. (To lubricate, wipe off grease and reapply after
lubricating between plates.)

It is dangerous to use below the safety ratio inTable 2 as it may result in pin rotation and a reductionin strength. In addition, even if the safety ratio in Table2 is followed, insufficient lubrication may also causethe pins to rotate. Always lubricate the chain regularly.
5.
Selection
1. Determine the following based on usage conditions.
Chain speed
Number of repetitions per day
Work load (including inertia and impact strength)
When a chain speed of 30 m/min or 1,000 cycles/day is
exceeded, Leaf Chains may be inappropriate due to wear.
Use an RS Roller Chain.
2. Determine the type of chain.
BL Type is recommended.
Limit use of AL Type to applications with no impact load
or wear considerations (under 100 cycles/day).
3. Determine chain size using the following formula.

Fit Bore sprocketBore diameter is finished to an H7 tolerance, andthe keyway tolerance is JIS Js9 tolerance. Includesholes for set screws. Can be used as is withoutfurther additional machining.
Use sprockets with hardened teeth when high toothstrength and increased wear life are required.Sprockets with small numbers of teeth and StrongType RS Sprockets have hardened teeth.
The sprocket teeth have not been hardened.RS Sprockets with large numbers of teeth haveunhardened teeth.
Lock sprocketTightening the bolts will create frictional force on thetapered sleeve that will tightly secure the sprocketto the shaft. No troublesome keyway machining isneeded on the shaft side, making it easy to mountand align phases. Removal is also a snap.

Please include the product code and model number in your order.
Ordering Example
Product Code Model Number No. of Pieces Unit
Model Numbering Example
Sleeve Mounting ConfigurationConfiguration A Configuration B
Configuration A
Direction of movement Direction of movement
Configuration B
When mounting a Lock Series S Type sprocket, the sprocketwill move 0.5mm – 1.0mm in the direction of the shaftbetween the time the sprocket is initially secured and thetime the sprocket is tightened. Therefore, take this move-ment into consideration when centering the sprocket. Theamount of sprocket movement varies with the type. (See theillustration on the right.)
Allowable transmission torqueEnsure that the load torque does not exceed the specified transmission torque in the dimension table.Shaft diameter tolerance and surface roughnessUse a shaft diameter tolerance of h8 and a surface roughness degree of 12S as your standards.Mounting to shafts provided with keyways or D-shaped shaftsThe allowable transmission torque will decrease by 10% when mounting the sprocket to a shaft provided with a finished keyway, such asa motor shaft, or to a D-shaped shaft.Mounting to cold finished carbon steel barsThe allowable transmission torque will decrease by 10% when mounting the sprocket to a cold finished carbon steel bar (drawn steel withan allowable diameter of 8 – 10 class).Ensure that the shaft is a solid shaft using S35C grade or higher steel.Operating temperature range: -20 to 200Always use a torque wrench when tightening the bolts. (Refer to the torque wrench operation manual for proper use.)

Applicable models: RS35 – RS100 1B Type RS SprocketsAllows RS standard sprockets to be mounted to shafts without using keys.
Lock Series
1. No wobbling after mounting (tightening)2. Easy phase alignment
3. Easy mounting and dismounting4. No retainers required
The inner diameter of the sprocket and the outer diameter of the lock sleeveare tapered. When the mounting bolts are tightened, the sprocket will slide andmove up on the tapered surface. A wedge action will generate force P andforce P’ in the radial direction to press on the shaft and tapered inner side, andfrictional force will tightly secure the sprocket and shaft.
The same sleeve is used for all models, so some holes maynot be used. Check the installation guide that comes with theproduct before attaching the mounting bolts for use.

(Ex.) RS35 chain, Required no. of teeth: 15, Required bore dia.: 11mm
Use an N211 sleeve. “XX” in the table refers to bore diameter. Maximum transmission torque will be 46Nm.
Applicable models: RS35 – RS60 1B Type RS SprocketsAllows RS standard sprockets to be mounted to shafts without using keys.
Features 1. Greatly increases work efficiency
2. Suitable for small shaft diameters
3. Compact design
Unlike conventional products that require a number of tightening bolts, this type can besimply tightened with a nut and coupled to a shaft with ease. Furthermore, it can be easilydismounted for fine-adjustment and mounted again.
Features a compact design with strength calculations that take the maximum allowableload of the chain in mind while eliminating any waste.
Tsubaki offers standard models with diameters ranging from 7 – 28mm to match awide-variety of customer needs.
Allowable transmission torqueEnsure that the load torque does not exceed the specified transmission torque in the dimension table.Shaft diameter tolerance and surface roughnessUse a shaft diameter tolerance of h8 and a surface roughness degree of 12S as your standards.Mounting to shafts provided with keyways or D-shaped shaftsThe allowable transmission torque will decrease by 10% when mounting the sprocket to a shaft provided with a finishedkeyway, such as a motor shaft, or to a D-shaped shaft.Mounting to cold finished carbon steel barsThe allowable transmission torque will decrease by 10% when mounting the sprocket to a cold finished carbon steel bar(drawn steel with an allowable diameter of 8 – 10 class).Ensure that the shaft is a solid shaft using S35C grade or higher steel.Operating temperature range: -20 to 200Always use a torque wrench when tightening the bolts. (Refer to the torque wrench operation manual for proper use.)

Pin Gear Drives
Chain-type Pin Gears
For linear drive and large radius rotary drives, a chain gear drive is used by a drive source (motor, etc.) through a reducer.Chains require a large space, and gears need precision machining, which can lead to high costs and other issues. Pins gearsare perfect in these situations.An attachment chain is wound around the outside of a drum in place of a gear drive wheel, and a specially machined sprocketis used for the pinion gear. For linear drives, the attachment chain is attached linearly and used in place of a rack.
Unlike sprockets where the chain wraps around them, sprockets for pin gears engage the chain, which requiresthem to have special teeth profiles. Using a unique principle, Tsubaki’s special tooth profiles are designed forthe lowest possible backlash and enable smooth engagement. Especially, the tooth profile changes to matchthe mounting diameter of the pin gear chain in inner/outer rotary applications for the optimal pin gear drive.
Contact a Tsubaki representative for more information.
The following is a rough comparison of pin gears and gear racks.

Pin Gear Drives
Pin Gear Drive Units
A pin gear drive unit is a drive unit with a pin gear and engaging pin rack (or pin wheel) set.
Features
Simple installation, rough mounting OK
Segmented units allow for assembly on large equipment
Larger transmission power than chain types, enabling small sized operations.
Construction
Pin gears feature special tooth profiles for smooth, continuous
engagement with the rollers. Teeth have been hardened toincrease their strength and wear resistance.
Usage Examples
Unique Pin Gear Tooth Profile
The pin gear tooth profile is an approximation of an involute curve to provide smooth engagementand power transmission between pin wheel and rack. They also incorporate a unique Tsubakidesign to give them even further strength.
Pin Rack Pin Gear Pin Wheels Pin Gears
Pin wheel diameter (number of pins) can be designed freely.
Pin gear
Pin rack Roller
(Sample model no.)PDU35-GW-75P/150P (semicircular)/19T(Application) Drive for branching
equipment on a powder conveyor
Easier to assembly than a chain-type unit.
A new drive system to replace gears and racks.
Construction
Linear Drives Rotary Drives
Pin rack length (number of pins) can be designed freely.
Both the pin racks and pin wheels use hollow pins for installation, making iteasy to use the hole for mounting.
With racks, the joining faces can be aligned to ensure unit pitch spacing ismaintained and to enable long linear drive.Pin wheels for large equipment are also segmented for assembly, enablinglarge diameter pin wheels.

1. Provisionally select pin gear drive unit pitch diameter
2. Calculate tangential load Fw of the load
For rotating movement :
For linear movement :
Provisionally select the pitch diameter of the pinwheel from the size of the rotating equipment.Provisionally select the pitch diameter of the
pin gear from the reduction ratio.Provisionally select the pitch diameter of thepin gear from the equipment layout.
Calculate tangential load Fw of the load acting on the pin wheelor pin rack from the load conditions.
3. Calculate corrected tangential load FtFind the usage factor Ks (Table 1) from the operating conditions and the speedfactor Kv (Table 2) from the tangential speed and determine the correctedtangential load Ft by multiplying the above with the tangential load Fw of the load.
4. Select the pin gear drive unit frame modelSelect a pin gear drive unit frame model that satisfies the conditionsbelow from the allowable tangential load Fp and the correctedtangential load Ft of each pin rack or pin wheel frame model.
5. Select the model numberSelect the number of rollers of the pin wheel with a pitchdiameter closest to the pitch diameter of the pin wheelprovisionally selected and the selected frame model.Find the number of rack rollers from the selected framemodel and the running distance (or the stroke distance).Select the number of teeth of the pin gears with a pitch
diameter closest to the pitch diameter of the pin gearprovisionally selected and the selected frame model.
Allowable tangential load Fp > Corrected tangential load Ft
Pin wheel :
P in rack :
Pin gear :
The protruding surface of the pin wheel frame has been machined to be concentric with the rollermounting holes. The frame acts as a centering reference plane, allowing it to be mounted by pressfitting it into the centering section of the equipment. The precision of the equipment’s centeringsection should be finished as per the Centering Section Precision table below.Calculate the parallelism between equipment beforehand so that the parallelism between the
installation reference plane on the pin rack side and the pin gear center fall within the Gear CenterParallelism table below.Install the pin rack so that the positions of A and B on both connecting elements fall within the tablebelow.

Table 3TH Type
Bolt Tightening TorqueWhen installing the tensioner on a base after attaching the idler sprocket
to the tensioner, be sure to fasten the idler sprocket and the tensioner
securely with a bolt. The table on the right indicates the tightening torque.
Be sure to use bolts with a strength classification of 8.8T or more.
When setting the tensioner, adjust with a shim so that thecenter of the idler sprocket and chain are aligned.
Position adjustment
If the idler sprocket is anchored in place, check whether ornot the sprocket can turn smoothly. If it does not turnsmoothly, the bolt may be too tight. Loosen the bolt and thenretighten properly.

Slackness in the chain can cause chain vibration and noise, and improper engagement with the sprocket, as well as
preventing the chain from operating properly. The Tsubaki Chain Tensioner adjusts slackness in the chain to enable
continuous and proper chain operation.
There are four types of Tsubaki Chain Tensioners: Our new TH Type (straight type, with idler sprocket), the TCS Type (swing
type, with idler sprocket), the ETS Type (straight type, with idler sprocket), and the TA Type (straight type, with plastic shoe).
The Tsubaki Chain Tensioner is composed of amain unit and an idler sprocket. (The TA Type is aunitized construction with plastic shoe.) Thetensioner's main unit employs the elasticity of abuilt-in coil spring to tension.

Remove the main unit of the TCS or ETS Type tensioner, the idler
sprocket, attachment bolt and washers from their packaging, and
assemble them as shown in Fig. 1. The plastic shoe for the TA
type comes as part of the main unit and no assembly is required.
One flat washer should be installed on each side of the idler
sprocket. However, the CT-TCS80 and CT-ETS80 should have
two washers installed on each side. The idler sprocket attachment
bolt and flat washers are included with the idler sprocket.

Always insert the spacer where indicated(positions A & B) as shown in Dia. 8 wheninstalling the idler sprocket on thetensioner. (Failure to insert the spacer willresult in tensioner contact with the rollerchain. See Table 5.)
Attach the hub so that it faces the tensionerwhen installing ball bearing type idlersprockets. When attaching on the oppositeside, install the number of spacersindicated in parentheses in Table 5.
Once the round head bolts
are attached to the tensioner
as shown, attach the adapter
and tighten the nuts just until
snug.
The tensioner stop should be positionedfacing down (spring facing down) as per thediagram on the left.

Once the drive and drivensprockets have been aligned, fixthe adapter to the attachment areausing a mounting bolt (“C” indiagram, bolt not included).
Once the chain is engaging the sprocket, tighten the adaptermounting nuts (“D” in diagram). Next, after inverting thetensioner stop as shown by the arrow in Dia. 9, removing thehexagonal screw will activate the spring. Installation is nowcomplete. Check the condition of the roller chain sag and theinstallation itself.

Always install chain tensioners on the roller chain sag side.Tensioners cannot be installed on the tension side or usedwhen the chain is run backwards.
Then, within a range wherethe roller chain does notcontact the tensioner unit,ensure the force of the rollerchain moves as perpendicula ras possible to the A-A line.(Tensioner is a swing typeunit.)
3)
Temporarily tighten the
tensioner with two bolts. At
this time, adjust with a
shim, etc., so that the
center of the idler sprocket
and roller chain are aligned.
(Fig. 6)
3)
Push in on the chain with the tensioner and, if the amount ofslack is appropriate (), tighten the nut and anchor the tensioner.Aim for a value less than = 0.02 x L. (Fig. 7)
4)
Adjust with a shim, as shownin Fig. 3, so that the center
of the roller chain and idler
sprocket are aligned.
4)
Open a hole in the base
that holds the tensioner. (Aslotted hole is convenient.)
5)
Push in on the chain with thetensioner and temporarilytighten the tensioner to thebase with a bolt. (Fig. 4)Then tighten the hexagonalscrew and anchor so that theswing angle is about 15.

Open a hole in the attachment base. In this case, two bolt
holes are required, but a hole that is as long as possible will
make positioning simpler, and the re-tensioning operation
will be easier when the chain elongates.

Operating temperature: -10 to 60 (Contact a Tsubaki representative for use in special environments.)Use the Tsubaki End Fitting Bolt Connecting Link when connecting an end fitting bolt and an RS RollerChain. We recommended disassembling and lubricating regularly for safety.Do not use M-type connecting links for RS Roller Chains (that have a gap between the pin andconnecting link plate) or offset links.Use only RS Roller Chains. These end fixtures cannot be used with Lube-Free Drive Chains, Heavy
Duty Roller Chains, Super-H Roller Chains, and Ultra Super Roller Chains. (When using a SuperChain, always use a Super Chain connecting link.)Grease the surface of the connecting link pin in advance when attaching the end fitting bolt and RSRoller Chain. Take care to attach precisely and avoid twisting the chain.Attach so that there is no bending load on the end fitting bolt.Do not subject the threads or head of the end fitting bolt to impacts or cause them to become distorted.

Automatic Lubricator for Roller ChainOperating principle
Notes on Usage
Turning on the gas generator switch generatesH2 gas, the pressure of which pushes down ona piston and releases oil from the bottom of thelubricator. Setting the time adjustment dialallows users to control the amount of H2 gasgenerated for 1 – 12 months, thereby adjusting
oil flow in one single step.
The amount of oil dispensed varies withambient temperature. Especially, the amountof oil released will be lower in lower tempera-tures, so the dial should be set to a lowervalue (shorter than your desired dischargetime). (See diagram on right.)
The length of the lubrication path (piping)should be less than 0.5m, with an innerdiameter greater than 6mm. The pathshould also not be segmented.
CAUTION: Do not use where exposed toflame or direct sunlight.
Do not use where oil may contact or mixwith food.
When stopping oil discharge midway, besure to set the dial to zero “0.”
InstallationPosition the lubricator with the optional brushattached on the chain sag side so that oil canpenetrate between the outer and inner plates.This will ensure the area between bushes androllers are lubricated as well. The lubricatorbrush should lightly touch the chain plates.(See diagram on right.) Secure the optionalclamp by drilling a tap hole in a bar or the likeand securing with an M4 bolt, or by drilling ahole that an M4 bolt can pass through andsecuring with a nut. (See diagram on bottomright.)
Caution:The automatic lubricator should be used with rollerchains operating in the “brush lubrication” or “driplubrication” range. This product will not provide enoughlubrication for roller chains used in the “oil bath” or“forced lubrication” range and should not be used.

Align the Chain ElongationScale with the pin.
The chain elongation scale allows for quick checks of a chain's pitch elongation limit.Used to check chain elongation on RS Roller Chains, BS Roller Chains, and Leaf Chains to determine whenit is time for the chain to be replaced.
Safety PrecautionsDepending on the attachment and chain size, there may beinterference with the Elongation Scale for specialty
attachment chains or K2 attachment chains catalog item.Check chain elongation at the location on the chain wherethe sprocket teeth engage the most.Check chain elongation at a location on the chain wheretensile force is applied.
Do not use the scale for any purpose other thanmeasuring chain elongation.
Always turn off the power switch to the equipment andconfirm that it has come to a complete stop beforechecking chain elongation. In addition, make sure that theswitch cannot be turned on accidentally.
Check where along the scale the pin is positioned(pitch indicated in parentheses).

Table 1: Multi-strand factor
Table 2: Service factor Ks
Figure 1: Shock factor K
Table 4: Imbalance load factor Ku
Number ofroller chain strands
The load borne by multi-strand roller chain is unequal
across the width of the chain, and thus it cannot be
expected that the transmission capacity will be equal
to the capacity of a single-strand roller chainmultiplied by the number of strands. For this reason,
the transmission capacity of multi-strand roller chain
is obtained by multiplying the transmission capacity
of single-strand roller chain by a multi-strand factor.

The kW ratings are based on conditions of minimal
load fluctuation. Depending on the degree of load
fluctuation, it may be necessary to correct the
kilowatt ratings using the service factor Ks.
Use Table 2 below to determine the appropriate service
factor based on the type of machine and the source
of power.
The design kW value is obtained by multiplying thekilowatt ratings by the service factor.
Belt conveyors with little load
fluctuation, chain conveyors,
centrifugal pumps, centrifugal
blowers, ordinary textile ma-
chines, and ordinary machines
with little load fluctuation.
Centrifugal compressors, marine
engines, conveyors with moder-ate load fluctuation, automatic fur-
naces, dryers, pulverizers, gener-al machine tools, compressors,
general construction machines,general paper mill machines.
Presses, crushers, construc-
tion and mining equipment,
vibration machines, oil well
rigs, rubber mixers, rolls, roll
gangs, general machines with
reverse or large-impact loads.
Table 3: RPM factor Kn and number of teeth factor Kz
This coefficient is determined by the ratio of the
moments of inertia between the prime mover and the
driven machine (rate of I, GD2), and the amount of
backlash in the transmission device.
When the inertia ratio R is greater than 10, use R = 10.When the inertia ratio R is less than 0.2, use R = 0.2.
If I or GD2 of the prime mover or driven machine is
unknown, use the value of R in Figure 1.

Imbalance load factor KuWhen carrying out shuttle traction and lifting with two
chains, or four chains for shuttle drive and lifting, the
chain tension will not be uniform. This must be accounted
for by multiplying the following imbalance load
coefficient Ku to adjust the left-and-right load imbalance.
Example: For four lifting strands, the imbalance load
factor for one strand Ku= 0.6 0.6 = 0.36

1. Example: Single-strand chain, design kW=7kWHow to use this table (Fig. 2)
(3) Please allow for a drop in the kW rating values
shown in the design kW ratings chart (Fig.2)
when 1-pitch offset links or Super 4POL are
used.
Assume that the speed of the small sprocketis 100 rpm. Judging from the intersecting
point of design kW value of 7 kW (vertical axis)
and the speed value of 100 rpm (horizontal
axis), RS80 and a sprocket with between 13
and 18 teeth would be appropriate. Therefore,
based on the position of the intersection, we
can see that a 15T sprocket can be used.
Assume that the speed of the small sprocket
is 200 rpm. Following the same procedure
shown in the above example, RS80 and asprocket with less than 13 teeth or RS60 and
a sprocket with more than 18 teeth would be
appropriate. This table is used for tentative
selections only. The kW ratings tables should
be used to confirm the chain sizes.

Even if the fractional part of the value found for L (below that of the
decimal point) is small, round it up to the nearest integer and add a link.
An offset link must be used when an odd number of links exist. However,
if possible, change the number of teeth on the sprocket or the distance
between shafts so that an even number of links may be used.

Starting frequency

Step 2
Step 3
Step 7
Step 8
Step 6
Step 4 5
For small sprockets,
use Z' ≥ 15T
For large sprockets,
use Z < 120T
Use the Provisional Selection graph totentatively determine the chain size and
the number of teeth Z' of the small sprocket
From the kW ratings tables,
is the selected chain kW ratings
greater than the design kW?
Steps 4 and 5(1) Select chain and number of
teeth of small sprocket
Use the provisional selection graph
(Fig. 2, 3 and 4) or the kW ratings
tables to obtain a chain and small
sprocket number of teeth that satisfy
the revolution speed of the high-
speed shaft and the transmission kW.
Select a chain with the smallest pitch
that has the required kW ratings.
If a single strand chain does not have
sufficient power, select a multi-strand
chain. If site restrictions require a
short distance between shafts and
the smallest possible sprocket outer
diameter, use a multi-strand roller
chain with a small pitch.
(2) Select number of teeth for largesprocket
Once the number of teeth of the small
sprocket has been decided, the
number of teeth of the large sprocket
is determined by multiplying the
number of teeth of the small sprocket
by the speed ratio.
The number of teeth of the small
sprocket should be at least 15.
However, it is not desirable if this
causes the number of teeth of the
large sprocket to exceed 120. In thisevent, the number of teeth of the
small sprocket must be reduced;
however, it is recommended to use
more than 13 teeth.
Step 7When the number of links is odd
If the number of links is odd, it is
best to avoid using an offset link
and instead change the distance
between shafts so that the numberof links is even. If the one-pitch
offset link of RS roller chain or the
four-pitch offset link of Super chain
is used, allow for a decrease of
transmission power as explained in
the notes in the kW ratings tables.

(Step 1) Required data
(Step 2) Determine the service factor
(Step 3) Determine the design kW
(Steps 4 and 5) Determine the chain and the numberof teeth for the sprocket
Decide on the chain number and number of teeth of thesmall sprocket derived from the speed of the high speed
shaft, at 90 rpm, and the design kW (14.3 kW).
(1)17T for single strand RS100 is derived from the basic
selection figure and the kilowatt ratings table. Since the
speed ratio is 1/3, the number of teeth will be 17T and 51T for
RS100. But, with an outer diameter of 17T at 189 mm and
51T at 534 mm, these are not adequate because they do not
fit in the required space. 189 + 534 > 700
(2) Checking multi-strand chains:
19T and 57T for RS80-2 is derived with double-strand chain,and the outer diameter of its sprockets are 167 mm and 476
mm, which is within limits. Check RS80 kilowatt ratings table
for the kW ratings of 19T for RS80-2.
The kW ratings for the small sprocket number of teeth (19T) is
5.06 kW at 50 rpm, and 9.44 kW at 100 rpm. By calculating
proportionally using the differences in their tables, drive kW
for 90 rpm is 8.56 kW.
(3) This 8.56 kW is the kilowatt rating of single-strand chain, and
the kilowatt rating of double-strand chain that will be used is
derived from the multi-strand factor in Table 1.8.56 kW X 1.7 = 14.6 kW
(4) This kW rating, 14.6 kW, satisfies the design kW (14.3 kW).
(Step 6) Check the bore diameter(1) Check the bore diameter on the dimension table. Maximum
bore diameter for RS80-2-19T is 63 mm, and it can be used
for the required bore diameter of 45 mm.
Maximum bore diameter for RS80-2-57T is 80 mm, and it can
be used for the 60 mm.
(Step 8) Check lubrication method
Since the small sprocket is RS80-2-19T at a speed of 90 rpm,according to the kilowatt ratings table, lubrication method A will
be used. It is necessary to use oil bath lubrication or lubrication
with a slinger disc.
(Step 7) Determine the distance between shafts
With a distance between shafts of 350 mm,
, and it will fit into the required space.
Number of the links is calculated as
In order to have an even number of links, raise the value
to the right of the decimal point to an integer to get 70.
For selecting lifting or shuttle traction applications, do not use the
General Selection method. Use the Allowable Load Selection method.

(1)For transmission with large shocks
and other extreme conditions, in
particular large-load transmission
and transmission where a thrust
load may operate, use F-type
connecting links or two-pitch
offset links.
(2)When using a one-pitch offset link,
or a Super Chain 4 pitch offset link,
make the following allowances forstrength with respect to the
maximum allowable load
M-type CL*: 100%
F-type CL: 100%
Two-pitch offset link: 100%
(Reference)
One-pitch offset link: 65%
4 pitch offset link: 90%
(Super Chain single strand)
One and two-pitch offset link: 60%

(3)There is a possibility that the rim
or boss of commercially available
cast iron sprockets are not
strong enough for the high
tension of Super Chain, Super-H
Roller Chain, and Ultra Super
Chain. A type, B type, and C
type RS sprockets are suitably
strong.
(Use SS400, S35C, SC450, etc.)
(4)For high-speed sprockets, use a
sprocket with hardened tooth
tips.
(5)Be sure to lubricate roller chain,
as the bearing pressure rises
very high.

RS140-1 cannot be used because its maximum allowable load is 4100kgf.
RS140-SUP-1 can be used because its maximum allowable load is 5500kgf.
Since the sprocket bore diameter of 18T is up to 89 mm, and for 26T is up
to 103 mm, it can be used with a drive shaft diameter of 66 mm and driven
shaft diameter of 94 mm.With the distance between shafts at 500 mm, a sprocket with 18T
(d=255.98) and 26T (d2=368.77) can be used.

Lubricate the chain joints as much as possible after you reduce the loads. Sufficient lubrication is also
required at end fittings (end bolts and connecting links, etc.) and connecting parts, etc.
Use F-Type (semi press-fit) connecting links. M-Type connecting links can only be used if there is
minimal shock with no lateral force. Offset links cannot be used.
If there are any laws or guidelines for chain selection, check and calculate accordingly. Make sure to
follow the manufacturer's selections and select the safer of the two selections.
9. Example of shuttle traction
The following are typical examples of using Roller Chain for shuttle traction. The roller chain can be attached to the shutttle
with an end fitting and towed using a sprocket on one end (left figure), or the driving unit can be attached to the shuttle, with
a roller chain fixed to both ends using end fittings (right figure).
There are similar ways to tow a shuttle at an angle. With the left figure the drive sprocket would be set at the top of the incline.

10. Pin gear drive selection method
Generally, linear movement or large radius rotation is made possible by a roller chain and gear through a transmission source
(motor, etc.) via a reducer.
A roller chain, however, needs a lot of space, and gears require precision machining, which increases the cost. A pin gear is
ideal in these situations.
Roller chain Gear Pin gear (Linear) Pin gear (Rotary)
For pin gear drives, a roller chain is wrapped around the perimeter of a drum to make
a wheel, and special sprockets (see Sprockets) are used instead of pinion gears. For
linear motion, a roller chain is attached and used linearly instead of a rack.

Rough installation accuracy and no precision machining required for gears.
Grease lubrication can be used.
A pin gear is not suitable for ultra precise drives, and the noise level is high compared to gears.

10.2 Chain installation and precautions
10.1 Characteristics of pin gears
1) When used linearly (rack) with rollers facing up:
Connecting links are used on both ends, and fittings are attached and bolts and nuts are fastened to remove any slack. (Both
ends need to be secured snugly with double nuts.) NOTE: This is not recommended as tooth slipping and interference can occur.
Attach K1 or SK1 attachments every 2nd
link and fasten with bolts and nuts every 2nd
or 4th link with chain pulled taut so there is
no slack or meandering. (K attachments are recommended.) The attachment holes are usually processed on-site.

Use bolts with a strength class 8.8 or higher (JIS1051-2000 Tensile strength 800 N/mm 2 or higher). (SCM435 heat treated
bolts, etc.)
Attach K1 or SK1 attachments every 2nd
link and fasten with bolts and nuts every 2nd
or 4th link with chain pulled taut so
there is no slack or meandering.
Adjust the shaft of the sprocket so that the sprocket engages the chain straight.
The clearance () between the rollers and the bottom of the sprocket teeth should be less than the dimensions shown
in the following table. The bottom of the teeth and rollers should not touch each other.
When the bottom of the teeth and rollers touch each other in the clearance described above, the tooth form needs to be
pre-designed with larger clearance . Contact a Tsubaki representative for details.
2) When used linearly (rack) with rollers facing down:
3) When wrapped partially or totally around the outside of a drum:
Attachment chain length is in the range of -0.05 to 0.15% of standard length
(nominal pitch x number of links). When the chain is wrapped around a drum,
shims need to be used between the drum and the chain attachments to
eliminate slack.
Since K attachments can be adjusted with shims, they can be attached onto
the drum more easily than SK attachments.
When the drum is not perfectly round, the thickness of the shims needs to be
adjusted while the chain is wrapped around the drum so the radius is circular.
As shown below, a dial gauge or a surface gauge can be used for adjustment.
Process tap holes to fit the holes of the chain attachments.
4) When wrapped partially or totally around the inside of a drum:

11.3 Selection method for Stainless Steel Roller Chain (SS and NS series) at high temperatures (400 or higher)
As the temperature of a chain increases, its strength decreases. The usage limit at high temperatures is determined by thetemperature of the chain itself. Contact a Tsubaki representative when using stainless steel chain at ambient temperatures of400 or higher. However, chain cannot be used at 700 or higher. When a chain is selected using the temperatureselection method, the chain speed must be below the maximum speed of the allowable load selection method.Changes and cautions associated with high temperature environments are: 1) All clearances need to be abjusted to prevent poor articulation and poor roller rotation due to thermal expansion. 2) The chain may break (creep rupture) under low loads as the temperature increases.
1) The maximum allowable tension for Corrosion Resistant Chain is low compared to Standard RS Roller Chain (excluding NEP).2) Avoid using offset links when possible.
3) Refer to the following page when acid or alkali solutions or chemicals will come in direct contact with the chain.

1. How to Cut Roller Chain
If the chain you purchased is either a unit length (3,048mm) or on a reel, it is necessary for you to cut the chainto the necessary length.
How to cut a roller chain
Using a chain vise and punch
Using a chain breaker
1. 1 Using a chain vise and punch
For riveted type roller chain, grind down one end ofthe outer plate's two pins (same side) to the surfaceof the plate. Be careful of the chain overheatingduring the grinding process.This process is unnecessaryfor Poly Steel Chain as there are no rivets. As RS08B-1to RS16B-1 use easy cutting pins, the rivets do notneed to be ground.Remove the cotter pin for cotter pin type roller chain.
1)
2)
Grind the rivets of the pins untilthey are flush with the plate.( )
Fig. 1 Rivet-type roller chain
Fig. 4 Tapping the pin with the primary punch
Fig. 2 Grinding the pin ends
Place the roller chain into the groove of the chainvise (see Accessories Section) and tighten thevise to secure the roller to be disassembled.
Follow 1.3 and 1.4 for Poly Steel Chain andLambda chain.
For multi-strand Super Roller Chain, place thelowest roller into the groove of the chain vise.
3)
Use a secondary punch (see AccessoriesSection) to remove the pin completely from theouter link plate. Check to make sure that the bush
where the pin was removed has not come looseor deformed. Do not use if loose or deformed.
5)
Fig. 3 Setting the roller chain in the chain vise Setting Super Roller Chain
Primary punch
Outer plate
Vise
Place a primary punch(see Accessories Section),according to chain size, onthe head of the ground pin,
and then hit the head ofthe primary punch with ahammer. Make sure to hitthe pins alternatively toensure the pins are removedevenly and at the sametime. Continue to tap the pin until just before thepin is removed from the outer plate.
4)
Safety precautions
Make sure to use a grinder when grinding theriveted portion of one end of the rivet-type pin.If it is extracted without being ground first,more time and effort will be spent, and will
damage the chain.Do not reuse any removed parts.
1. 2 Using a chain breaker
For riveted type roller chain, grind down one end ofthe outer plate's twopins (same side) to thesurface of the link plate.(Same as 1.1) Removethe cotter pin for cotterpin type roller chain.Remove the two pins
from the same outerplate. Check to makesure that the bush wherethe pin was removed has not come loose or deformed.Do not use if loose or deformed.
1)
2)
Fig. 5 How to cut a chain using a chain screw
Safety precautions
A chain breaker (see Accessories Section) is atool made for cutting chain, and can cut rollerchain that is set on a machine. In this case, it isnecessary beforehand to support the load onthe roller chain and the weight of the roller chainitself to prevent it from falling after being cut.Do not reuse any removed parts.
1. 3 How to cut Poly Steel Chain

Support the chain with a chain vise and grind down oneend of the outer link plate's two pins (same side) to thesurface of the link plate. Be careful of the chainoverheating during the grinding process. Grindingshould be carried out slowly so as not to overheat the
bushes in particular.Then cut the chain using an exclusive cradle (seeAccessories section) and an RS Roller Chain punch.Important points for cutting are outlined in 4) and 5) in1.1. However, use an exclusive cradle instead of a vise.Hit the pins alternatively when removing the pins with apunch. Take extra care not to remove or cause anydamage to the bush. Do not use bush if it has comeloose or been damaged.

2. How to Connect Roller Chain
2. 1 When connecting chain on sprocket teeth
Wind the chain around one of the sprockets so that both
ends of the chain are facing each other on the sprocket.
Insert the connecting link in the two end links of the chain.
Insert the connecting link plate of the connecting link and fasten
the plate using the clips/cotter pins or spring pins provided.
When using a press-fit connecting link or F-Type (semi
press-fit) connecting link, insert the connecting link plate
by tapping it with a hammer until it moves into position.
Then fasten it using
the clips/cotter pins or
spring pins provided.
When using the sprocketteeth to connect thechain, take care notto damage the teeth,particularly when usinga cast iron sprocket.
1)
When connecting or disconnecting roller chain, itis convenient to use the sprocket teeth. Pleasecarry out the following steps.
2)3)
4)
5)
2. 2 When connecting between shafts
Wind the chain around the sprockets and pull the chainends together using a chain puller (see Accessoriessection) or wire.Insert the connectinglink in the two endlinks of the chain.
Insert the connectinglink plate of theconnecting link and
fasten the plate usingthe clips/cotter pins orspring pins provided.
1)
If a sprocket cannot be used due to layout, followthe procedures below.
2)
3)
Fig. 8 Connecting on a sprocket
Fig. 9 Connecting between shafts
2. 3 Clip and Cotter Pins
ClipClips are used for small size roller chain (underRS60) connecting links. When connecting the chain,the clip should be inserted securely into the slot ofthe pin on the connecting link after the connecting
plate has been inserted on the pin. If the legs of theclips are spread too far they will not catch properlyand will fall off during operation of the chain, causingaccidents. Care should be takenwhen inserting them. The clip isgenerally installed opposite tothe direction of travel for thechain as shown in Fig. 10.
1)
Cotter PinsTsubaki cotter pins are heat treated for Standard,
Heavy-Duty, and Lambda Chain. The legs of the cotter pinshould be bent approx. 60 degrees. Cotter pins should not
be reused, and commercially available cotter pins other
than those produced by Tsubaki should be avoided.
2)

Safety Precautions
Avoid using offset links wherever possible byvarying the center distance between shafts orusing an idler.
In the case of pins and connecting link plate holes
being press-fit type with F-Type or other connectinglinks, please avoid widening the connecting linkplate hole or narrowing the pin diameter to makeconnecting easier, as this will result in a reductionin roller chain strength and cause an accident.
The outer link of cotter pin type roller chain canbe used as a substitute for the connecting link.However, due to the press fit connection, theouter link plate must be carefully driven ontothe pin parallel to the connecting link. If theconnecting link plate is installed without duecare to parallelism, chain damage or increased
wear may result. Use caution as per (2) above.
Do not reuse press fit type link plates that havebeen detached, as the detachment results in areduction in strength.

3. Roller Chain LubricationLubrication is very important in roller chain transmis-sion, and becomes especially important when stringentdemands are placed on chain performance.When lubrication is not complete, even the mostadvanced transmission device will not realize its full
service life. Under some conditions the device maywear out within a very short period of time. For thisreason, exercise special care with respect to lubrication.
The main reason for oiling and lubing roller chain is to
minimize wear elongation of the chain and prevent corro-
sion. Wear elongation is caused by wear between the pin
and bush in articulating parts.
1)
Roller chain is coated with oil before being packaged
(except for stainless steel chain). This oil is a high grade oil
that prevents rust and provides lubrication. The oil prevents
the wear that frequently occurs in the initial stage of
operation, and it works well with lubrication oil to maintain ahigh wear resistance.
2)
On the slack part of the chain, apply lubrication oil to the
gap between each outer plate and inner plate. At the same
time, apply oil between the bushes and rollers.
2)
Avoid wiping the oil coating off of delivered roller chain, and
avoid washing the chain with detergent or other cleaning agents.
3)
3.1 Oil application locationsRoller chain wear occurs from wear between each pin and
bush, and thus oil must be applied to these parts.
1)
For roller chain that does not articulate, oil the chain
sufficiently and then apply a thick layer of grease around the
roller chain to prevent corrosion.
Sufficiently lube end fitting connections, even if these do not
move.
2)
For roller chain that is used outdoors, contact with rain and
snow will remove the lubrication and cause harmful corro-sion, and thus a cover or other protection should be
installed.
If rain or snow does fall on the chain, remove the moisture
and then promptly lube the chain and coat it with a thick
layer of grease.
3)
3.2 Chain used for liftingIn general the chain has no catenary parts. If possible, remove
the load that acts on the roller chain before lubing the chain.
1)
1) SAE numbers (Table 1)
2) Commercially available lubrication (Table 2)
3) Examples of lubrication at low and high temperatures (Table 3)The following oils are available when roller chain is used at low or high temperatures. Regarding other brands, use an equivalent.

To verify sufficient lubrication is taking place, remove the chain and inspect the connecting pins and bushes. If the contact surfaces ofthe pins or bushes show tearing or a red or dark brown color, lubrication is generally not sufficient.
3.4 Lubrication systems and methods (Table 4)
Apply oil to thegaps in the pinsand inner links on
the slack side of thechain. A brush canalso be used.
Oil with sufficient frequency (in generalabout once every 8 hours) so that theroller chain bearings do not dry out.
Using a simplecase, this methoddrips oil suppliedfrom an oil cup.
For one strand of chain, drip about 5 to 20drops of oil each minute. Drip more oil onhigher speed chains.
The chain is runthrough oil in a leak-free casing.
If depth h from the surface of the oil to thelowest point the chain reaches is toodeep, the oil may heat up (80°C or higher)and deteriorate. The depth to which thechain descends in the oil should be about6 to 12 mm.
Stop operationbefore oiling.
Lubricationsystem Method
Drip Lubrication
Oil Bath
Use a slinger disc
attached to a leak free
case to splash oil on the
chain. The peripheral
velocity of the disc
should be 200 m/min or
higher.
If the width of the chain is
greater than 125 mm,attach discs to both sides.
The lowest point h reached by the slingerdisc should be about 12 to 25 mm belowthe surface of the oil. The roller chainshould not enter the oil.
Lubrication using a Slinger Disc
The oil is circulatedin a leak-free caseand cooled by apump. When thereare n strands ofchain, n+1 oilingholes are required,targeting the gapsbetween each part.

4. Layout and Installation of Roller Chain
4.1 Speed ratio and chain lapA roller chain transmission speed ratio up to 7:1 is
normally suitable; however, at very slow speeds a ratio
up to about 10:1 is possible. The chain lap between
the small sprocket and chain must be 120° or more.
For lifting applications, the angle must be 90° or more.
The minimum distance can be as short as desired as
long as the teeth of the two sprockets are not in
contact. The optimum center-to-center distance
between the shafts is 30 to 50 times the pitch of the
roller chain. However, if the load is variable, a distance
of 20 times or less is suitable.
4.2 Distance between shafts
The installation precision of the sprocket has a large
effect on the smoothness of roller chain transmission.
It also affects roller chain life.
Install the sprockets correctly as described below.
4.4 Horizon precision and parallelism of the shafts
4.3 Amount of slack
If possible, the lower side should be the slack side in roller
chain transmission. The amount of slack is appropriate
when the distance (SS') that the chain can be moved per-pendicularly by hand at the center of the slack side is 4% of
the span (AB). (For example, when the span is 800 mm, the
amount of slack should be 800 mm x 0.04 = 32 mm.)
In the following situations, this should be 2%:When the transmission is vertical or close to
vertical (a tensioner is required).
When the distance between the shafts is more
than 1 m.
When frequent starts are made with a heavy load.
When sudden reverse motion takes place.
2)
Unlike V or flat-belt transmission, there is no need to
apply an initial tension in roller chain transmission; roller
chain is normally used with a suitable amount of slack.
If too much tension is applied to roller chain, the oil film
between the pins and bushes will break, causing
increased wear and damage on the roller chain and
bearings. If there is too much slack in the roller chain,
the chain will vibrate and ride up the sprocket,
damaging both chain and sprocket.
1)
Roller chain will stretch slightly during the first few dozen
hours of use as the contact surfaces wear in (about
0.05%). This may result in too much slack in the roller
chain and may require adjustment of the slack.
A tensioner can be used if the layout is designed for it. If
you do not have a tensioner, move the shafts to adjust
the amount of slack. Once the chain is worn in, very little
stretching will occur.
3)
Verify Horizontal precision with a level.
Adjust the precision to within ±1/300.
1)
Use a scale to correct the degree of parallelism of
the shafts.
Adjust the shafts so that they are parallel to within
±1/300 = (A-B/L).

Secure each sprocket to the shaft with a power
lock, lock sprocket, or key (if needed use a collar,
set bolt, etc.).
4)
4.5 Layout ( indicates the driver side in the illustrations)1) General layoutIdeally, the line connecting the sprocket centers in the
roller chain transmission equipment should be close
to level. In a layout that is close to vertical, the roller
chain may stretch and fall off the sprocket. Thus, an
idler or tensioner should be used. If possible keep
the angle of inclination within 60°.
4.6 Lambda Curved Chain installation1) Installing the guideCompared to a standard chain, a Lambda Curved
Chain has a larger gutter between the pins and
bushes, providing a greater degree of freedom. For
this type of chain, please install a guide on the chain
so that it engages straight onto the sprocket.
2) Minimum lateral bending radius (r)Please manufacture the guide so that its minimum
lateral bending radius is equal to or greater than the
specifications shown below.
2) Layouts requiring cautionWhen the slack is on the upper side
When the center-to-center distance between the
shafts is short, move the shafts to adjust the
distance and slightly increase the tension.
When the center-to-center distance is long, insert
an intermediate idler under the slack part to
support the roller chain.
(1)
When the chain speed is fast and the load varies
Roller chain may vibrate if the natural vibration
frequency of the chain, shock frequency of the
driven machine, or chordal action of the chain
(vertical pulsation of the chain due to the polygon
effect) synchronize. In this event, use a guide
shoe (made of NBR or ultra-high polymer polyeth-ylene) or other device to stop the vibration.
(2)
When the centerline is vertical
Install a tensioner that can automatically eliminate
excess slack. This is particularly necessary when
the drive shaft is on the bottom.

5.1 Hardening the teeth
When there is a small number of teeth (24 or less), and the
speed is 1/8 or higher of the maximum rotation speed
indicated on the kilowatt ratings tables.
When using small sprockets with a speed ratio of greater
than 4:1.
When a large load is used at low speed (when using the
Low-Speed Selection Method).
When using under conditions that will cause the teeth to wear.
1)
When a sprocket is used under the following conditions,
the sprocket teeth must be hardened.
2)
5.3 Precautions related to additional processing
3)
4)
5.2 Number of teeth
As many teeth as possible should be used on the
sprocket on the high-speed shaft side to help ensure
smooth drive transmission. Generally, 15 or more
teeth should be used. However, when the speed ratiois high and the number of teeth on the low-speed
sprocket exceeds 120, chain engagement problems
can occur when there is even slight chain wear. In this
case, decrease the number of teeth on the high-
speed sprocket, but the number of teeth should still
be kept to 13 or higher. However, if the sprocket will
be used at extremely low speed and not subjected to
shock, a sprocket with 12 or fewer teeth can be used.
Shaft bore processing
Maximum shaft bore processing dimensionsThe maximum finished shaft bore size should be at or
below the size shown in the specifications for each
model number. Please contact a Tsubaki representative
if using standards other than the JIS standards key.
Finishing standards
When finishing, verify the standards for the tooth outer diameter ("DO"in the diagram) and the hub outerdiameter ("DH" in the diagram).Also, verify that the deflection onthe tooth root ("a" in the diagram)and the deflection on the end
surface of the tooth ("b" in thediagram) are at or below thevalues shown below.
1)
Sprocket weldingWhen welding a hub to Type A sprockets for use, thewelding can cause deformation or deflection of thetooth and surface, making it impossible to maintainproduct quality. As such, welding should be avoided.With Type A Strong Series sprockets, welding canalso decrease the hardness of the sprockets, soagain, welding should be avoided.Processing on the hub outer diameterDo not perform any additional processing to the outer
diameter of the hub. If processing needs to be
performed, please first contact a Tsubaki representative.

6. Chain Test Run
After installing the chain, carry out a test run and check the following items before you actually start running the chain.
6.1 Pre-test Run
Connecting link plates, clips, and cotter pins are
installed correctly.
Chain slack has been properly adjusted.
Adequate lubrication is available.
The chain is not touching the chain case.
The roller chain path is clean and free from obstructions.
1)
2)3)4)5)
6.2 Test Run
There should be no strange noises. Make sure thechain does not touch the case.Look for excessive chain vibration.Make sure the chain does not run up on the sprockets.Ensure that the chain is not jammed into the sprockets.
The chain should articulate smoothly.
1)
2)3)4)5)
Check the inspection checklist if there are any problems, and ensure roller chain and sprocket are correctly installed.
7. Roller Chain Inspection
In general, roller chain life is said to be reached when parts are damaged or when 1.5% wear elongation
occurs. See 6) in 7.3. Try to replace the chain before these conditions occur.If roller chain selection and operating conditions are suitable, you can expect rather long life with nounexpected trouble from the chain. However, wear will progress between the pins and bushes after longperiods. The following should be noted and inspected.

7.2 Inspection intervals
Regular inspection of roller chain is recommend atone month intervals. Inspection should be carried outat shorter intervals in:
Special or corrosive environments.High speeds with sudden stoppage.
Lifting or indexing operations.
1)2)
3)
7.3 Inspection requirements for ordinary transmission
Inspection lubrication conditionsDuring operation, check to see if there is lubrication in
the clearance between the outer plate and inner plate.
Also, check if the chain or rotating disc is immersed in
lubricating oil.
When the chain is stationary, the chain surface will
generally appear dirty from wear dust if lubrication is
unsatisfactory. This is especially the case between the
link plates.
When the chain is removed, connecting link pins and theedge of the inside of the bushes should be checked. If
there are any scratches, or red or reddish-brown
coloration, lubrication is improper or insufficient.
1)
Inspecting link platesIf repeat loads over the maximum allowable loadare put on the chain, there is a strong possibility offatigue breakage of the link plates. It is difficult tonotice initial cracking from fatigue breakage simplyfrom external observation.Usually, a crack develops at the edge of a holeor at the side of the link plate, as shown in the
illustrations below. The presence of cracks shouldbe checked carefully. Fatigue breakage progresseslittle by little, so it can be noticed with closeattention.
2)
Positions where cracksare likely to develop Example of a crack
Fig. 23 Cracks on the link plates
Fig. 24 Wear on the edges of the link plates
When wear occurs from sliding between the edgesof the plates and the guides, it is necessary toadjust the position of either the chain or theguides. The allowable wear on the link plates islimited to 5% of their height.
Inspecting PinsWhen the pins rotate, the roller chain must becompletely replaced with new chain. This alsoapplies to the connecting pins. By removing theconnecting parts it is possible to see the conditionsof wear and rust on the surfaces of the pins.
3)
Correct position Rotated position
Fig. 25 Rotation of the pins
Inspecting rollersAs with the link plates, if rollers are also subjectedto loads over the maximum allowable load, therepeated impact load between the chain and the
sprockets may cause fatigue breakage to occur.The roller should be checked in the same way asthe link plate.If foreign objects interfere with the engagement ofthe roller and sprocket, the roller may be damagedand a crack may develop. Careful attention shouldbe paid to the above. Furthermore, with high-speedoperations, even if foreign objects do not interferewith engagement, cracks may appear from theimpact with the sprocket teeth.
4)
Fig. 26 Cracks on the rollers
Chains damaged by fatigue breakage from therollers must be completely replaced, as each parthas received the same amount of repeated load.Also check for poor roller rotation.
Inspecting sprocketsChain and sprocket engagement can bechecked by observing the roller and teethsurface. Proper engagement is when the contactarea is uniform with point A in the illstration. If thecontact area is lopsided or the sides of the teethare wearing away (point B), this may have beencaused from improper installation of thesprockets or twisting of the roller chain. In thiscase, rechecking/readjustment is necessary.The normal point of impact is slightly up from thetooth root. However, when initial tension isapplied to the chain and tension remains on theslack side, the roller will slightly touch the tooth
root. However, point A receives the strongestimpact.

If a new roller chain is run on a worn sprocket, thechain will wear at a faster rate than normal. In thiscase, when replacing the chain, replacement ofthe sprocket is also recommended.
Inspection of chain elongationChain elongation is caused not by deformation ofthe link plate, but by wear on the pin and bush.Therefore, the remaining chain life can beestimated by periodically measuring the chainelongation.
Measuring chain elongationThe chain should be measured whilst stretchingit slightly to eliminate any slack.Measure the distance of the inside (L1) andoutside (L2) of the rollers at both ends ofthe measured links using a vernier caliper toget measurement (L).

Dimensions for evaluating standard length(chain pitch number of links) and 1.5% elongationare shown in Table 10 below.When the length of the roller chain cannot bemeasured with calipers, a tape measure maybe used; however, measurements need to be
taken over as many links as possible to reducemeasuring error.When chain elongation of Lambda/X-LambdaRoller Chain reaches about 0.5% it may belosing its lubricating properties. This may bedetermined by the adhesion of red wearparticles between the plates and the occurrenceof articulation stiffness. When this occurs, thelife of the chain has been reached.

As a general rule, roller chain should be used in a clean air flow; however, when used in special
atmospheres, refer to the various items that follow.
8. Cautions on Use in Special Environments
8.1 Use in wet conditions
An increase in wear elongation due to improper or insufficient lubrication.Decrease in fatigue strength from rust and corrosion (pitting) of the chain.
1)2)
If the chain is used in a sterilizing machine or water screen, for example, where the chain is splashed withwater or goes through heated vapor, the following problems may occur.
(1) Reduce bearing pressure by using a larger sized chain to improve wear resistance.(2) Use corrosion resistant roller chain for rust prevention.
8.2 Use in acidic or alkaline conditions
If roller chain is exposed to acidic or alkaline conditions, such as battery acid and liquid used in plating
processes, the following problems may occur.Embrittlement fracture of link plates and pins.
Fatigue breakage of link plates and pins due to rust and pitting corrosion.Wear from usual mechanical wear and corrosion.Reduction in volume of the whole chain from corrosion.In special cases where the chain is underwater (immersed in liquid),electrochemical corrosion may occur.There are also circumstances where even stainless steel roller chain willcorrode. Fig. 31 shows an example of chain that was used in a platingapparatus. The chain fell to pieces within one month due to the effects ofthe acid.
1)
2)3)4)5)
6)
1) Countermeasures
1) Countermeasures for embrittlement fractures (Stress corrosion cracking)
2) Countermeasures for corrosion
1) Countermeasures
Adopt a brittleness countermeasure that lowers crack susceptibility.Install a cover or casing to prevent acids or alkalis from contacting the
chain.Adopt a high-grade material with anti-corrosive properties.
Install a protective casing against dust.
Remove foreign particles by regularly washing the roller chain.Reduce bearing pressure by using a larger sized chain to improve wear resistance.Increase wear resistance by applying special processing to the parts of the chain where wear is a problem.
Use surface-treated chain.Install a cover or casing to prevent acids or alkalis from contacting thechain.Adopt a high-grade material with anti-corrosive properties.
In general, embrittlement fractures (stress corrosion cracking) occur aroundlink plate holes. This is the area where the pin and bush are press-fitted tothe link plate, and with the highest concentration of stress. Cracks aregenerated even when there is no tension on the chain. Roller chain ingeneral is more susceptible to acids than alkalis, and in special cases,embrittlement fractures (stress corrosion cracking) are generated by
seawater or pit water.
8.3 Use under conditions where wear is a problem
If the chain is exposed to highly abrasive materials that promote wear such as sand, coke, and metal
particles, the following problems may occur:When abrasive materials penetrate between the pins and bushes, chain wear is promoted and poor articulationoccurs.When abrasive materials penetrate between the bushes and rollers, chain wear is promoted and poor rollerrotation occurs.When the abrasive materials penetrate between the link plates, poor articulation occurs.

Symptom Possible Causes Remedy
9.2 Link Plate Related
Breakage of link plate.
Excessively large shock load.
Vibration in the chain.
Large inertia in the driven machine.(excessive load).
Corrosion.
Reduce shock loads by making the start-up, stopping, and
other actions smoother (installing a shock absorber, etc.).
Increase the size or number of chains.
Install an anti-vibration device (for example, a tensioner or
idler), Refer to "Excessive vibration in chain" page.
Increase the size of number of chains.
Replace with a new chain. Install a casing to protect thechain. Otherwise, periodically clean the chain.
Streching the link plate witha tensile load beyond its
breaking load will cause it
to strech and then break.
Static fracture
By repeatedly applying aload past its fatigue limit(fatigue strength), thefatigue will start at holesand then suddenly break.
Fatigue fractureOffset link plates are bent at
the center, and the resultingconcentration of stress at the
bend can cause a fatigue
break. Avoid using offset links
in high-stress applications.
Offset link plate fatigue
Remove all large or excessively repeating loads. Otherwise,increase the size or number of chains. Replace with a newchain.
Loads are greater than allowable.Crackes in the linkplates (fatigue), whichare perpendicular tothe direction of pull.
Excessive load.Deformation of linkplate holes.
Remove the cause of the excessive load. Replace with a
new chain.
The chain is being used in an acidicor alkaline enviroment. (This is not
caused by a repetitive load).
Corrosion stresscracks appear, usuallyas bow-shaped cracksin the link plate.
Replace with a new chain. Install a casing to protect thechain from the environment.
Consider a chain with a high resistance to corrosion stress
cracks. (Please contact a Tsubaki representative.)

Symptom Possible Causes Remedy
Symptom Possible Causes Remedy
Reduce shock loads by making the start-up, stopping, andother actions smoother.
Remove the large repetitive load. Otherwise, increase the
size or number of chains.
Excessively large shock loads.
Subject to a repetitive load greater
than the fatigue limit of the pin.Breakage of pin.
Install a casing to protect the chain. Periodically clean and
lubricate the chains.Corrosion.
The type of fracture foundwhen subjecting the chain tothe breakage test. Occurs when
chain is subjected to a load
greater than its breakage strength.
Static fracture
Occurs when the pin is repetitivelysubjected to loads greater than itsfatigue limit. Re-check the size of
the peak load and formulate a
countermeasure.
Fatigue fracture The pin is subjected to a large shock load and
breaks. The side with the initiating point receivestensile load, and the fracture progresses from
this point. A pin is especially susceptible to
becoming weak with regard to bending when
the surface of the pin has corroded. This type of
phenomenon occurs quite easily.
Shock-induced bending fracture
Replace with new chain. Improve the lubrication or loadingconditions.
Excessive load or improper lubrication.Pin rotates or begins tostick out.
Normal
Operating a chain at high load without
proper lubrication can create frictionbetween the pin and bush, causing
the pin to rotate. In this condition, the
pin may come out, leading to chainbreakage.
Replace with new chain immediately. Do not weld or
reuse the pins. (Dispose of the old chain to be sure that it
is not used again by mistake.) Also, if the pin head or link
plate surface is worn, check the installation.
Improper initial lubrication at installation. Replace the connecting link. If pin wear is excessive,replace the chain also. Take special care to properly
install the connecting section for devices such as end
brackets used for lifting applications, etc.
Wear or rust occurs onlyat the connecting pin ina lifting application orsimilar operation.
9.4 Bush / Roller Related
Roller and/or bushsplits. (Falls off)
Choose a different chain according to the kW ratings table.Excessive load or speed of rotation.
Replace the chain. Provide adequate lubrication accordingto the operating conditions.
Inadequate lubrication.
A bushed chain and not a roller chain is being used.
Roller does not rotate.The inner link plate is moving inward, or
the bush is cracked.
Replace with a new chain. Re-inspect the installation and
load conditions.
Periodically clean the chain. Install a casing to protect thechain.
Foreign particles have gotten betweenthe bush and roller.
Fatigue fracture.Reached the point of fatigue during operation and eventually broke. Impact withthe sprocket teeth at a force exceeding the chain's transmission capacity.
Roller is opening up.
Roller is becominghourglass shaped.
Excessive load.
Excessive load or inadequate
lubrication.
Reduce the load. Provide adequate lubrication.
Replace with new chain. Improve the lubrication or loading
conditions.
